lotse_purchases 0.1.0

In-app purchases and subscriptions for Flutter apps on a Lotse backend: products from the console, purchases checked with the store, entitlements.

0.1.0

First version.

• LotsePurchases.init() after Lotse.init, then LotsePurchases.instance.
• products(): the products of the Lotse console for this app, with price and title from the store. Google subscriptions per base plan; an offer the user may take (a free trial) is preferred.
• buy(product): the store dialog, the check by Lotse, and only then the purchase is finished in the store. Results LotsePurchaseSuccess (with provisional when Lotse could not be reached), LotsePurchaseCancelled, LotsePurchasePending, LotsePurchaseFailed.
• hasEntitlement('pro') synchronous from the cache, entitlements stream, current, refresh().
• restore() without a store dialog (StoreKit 2 Transaction.currentEntitlements, Google queryPurchasesAsync); a silent check of the store account at start, at most once a day.
• Open reports survive restarts and are sent again; a fresh purchase counts for 24 hours on the store's word until Lotse confirms it.
• The customer's UUID goes to the store with every purchase: Google obfuscatedAccountId, Apple appAccountToken.
• managementUrl for the store's subscription page.
